We discuss the possibility of interpreting the recent experimental hints, in favour of a 95 GeV resonance, with extensions of the Standard Model featuring an extra Higgs doublet and SM scalar (2HDM+s) or pseudoscalar singlet (2HDM+a). The possibility of reproducing the experimental anomalies will be compared with the theoretical constraints on the extended Higgs sector as well as complementary bounds coming from flavour physics as well as other colliders searchers. For both the 2HDM+s and 2HDM+a we will consider a generic natural flavour conserving (NFC) as well as the customary Type-I, -II, -X and -Y configurations of the Yukawa coupling to the BSM Higgs bosons.

  1. Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the $\mu$-Term Extended NMSSM

    hep-ph 2026-06 conditional novelty 6.0

    Viable μNMSSM regions can fit the 95 GeV diphoton/bb anomalies and produce H→hhs and A2→hA1→4b cascades near the 650 and (600,400) GeV CMS structures.

  2. Interpretation of LHC excesses at 95 GeV and 152 GeV in an extended Georgi-Machacek model

    hep-ph 2025-11 unverdicted novelty 4.0

    A minimally extended Georgi-Machacek model accommodates the LHC excesses at 95 GeV and 152 GeV while preserving the 125 GeV Higgs signal and the electroweak rho parameter near unity.

  3. Testing Viability of Benchmark Dark Matter Models for the Galactic Center Excess

    hep-ph 2025-09 unverdicted novelty 4.0

    Updated constraints on two simplified dark matter models for the Galactic Center Excess leave unconstrained parameter space after applying recent multi-experiment data.

  4. Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the $\mu$-Term Extended NMSSM

    hep-ph 2026-06 unverdicted novelty 3.0

    Viable regions in the μNMSSM accommodate the 95 GeV excesses within 2σ and allow heavy CP-even and CP-odd scalars to produce cascades close to current CMS sensitivity.
